Brookfield, Connecticut. The udu is an African clay drum evolved from water bottles carried on the head. Modern udus have holes on top and a second hole on the side (not shown here but on the back side of this piece). One can play either hole or both, covering either to create different kinds of tones and hollow sounds.
The Indian equivalent of the udu is the ghatam which is a water bottle with a single opening on top which is bigger than what is shown here.
